Our invention relates to improvements in. railway switch point pr0tectors,= and among the objects of the invention jarektoavoid wearing the terminals of switch "rails to a. ,knife edge by laterally shifting the wheels of a train so that the wheel flangeswill contact the switch rail at a point back from the entry edgeof said rail Where its cross sectionis of such thickness as to better 'revent split switchwrecks; and to provide a by Fig.1. I V I i a Fig. 3 is an end elevation of the parts disguard'plate which may be readilyadjusted torails ofdifferentheightand which is reversible so that when worn along one longitudinal margin itfmaybe turned over to presentlthe other margin and thereby greatly prolongthe life of's aid guard plate;

In order thatthe invention may be fully understood," reference wi ll nowlbe had to the accompanying drawing, .in which n Fig. 1 is a broken i elevation ofa rail equipped with the guard plate. Fig. 2 is a plan view of the parts disclosed closed by Fig. 2. a

Fig." 4' is a detail perspective view fof a filler block employed in carrying out the in vention. T r V;

Referring now in detail to-the different parts, A designates a railway rail, and B a switch rail of standard type.

2 designates the guard plate. which comprises a pair 'of reversible sections 4 and 6 having abutting inclinedi edges with interlocking notches or serrations 8 and 10, respectively, to prevent accidental longitudinal s ifting of the uppermostxsection upon the" lowermost section. The uppermost section 4 .v is also held from accidental .lateral'displace-z ment upon the lowermost section 6v by means of a longitudinalitongue 12which fits into a complemental groove 14 in the lowermost section. Theends of the sections a and6 are rounded or chamfered, as indicated at 16 to receive the impact of the wheel flange CLand shift the same laterally awayfrom the inner side of the rail head D, as shown by. Fig. 3, so that said flange C will not strike the end of the switch rail B. The sections-4 and 6' have inwardly-"projecting longitudinal; flanges 20 so that the flange "of sist thej wear incident to the repeatedzimpact of said wheelflanges in traffic; toprebeneath the base "of [tween the rail base and" the terminal 34' the-section'whichhappensto vbe uppermost will'fit, snugly against-the under surface (Z .of the rail head D.

-22 designates a filler block of metal 0'1: 1:

other suitable material; adapted to fill i the the rail A, and alsotoassist in} supporting the lowermostsection 5 of the guard platei v2. Said filler block 22 has upwardly. prof space between the lowermost flange 20and jectinglu gs 24; adapted to fitin comple- 2 mental" recesses 26- of the flanges 20 -andthereby prevent longitudinal displacement of said filler block 22.

The guard plate2 is firmly-heldin p csij tion against the; adjacent side-i of the rail A andthe filler block-22b a bracket 28 con l sisting of a horizontal arm 30v and a vertikey 36, which is driven between-theadjacent so' ands aid key is held; from longitudinal dis i placement after being driven inwardly be p by a cotter'f 40, which is placed through an opening inth'ef key ,andr 'bears against the 1 rear side of'the upturned terminal 34. 1

The sections 4 and 6 of the guardplate V 2 have cavities 42; and .44, respectively. so

that the one which happens to be lowermost Y may receive a lug 46' projecting inwardly from the vertical arm 32 of the bracket'28 and thereby secure the i. guard longitudinal displacement 1 With the partsc0nstructed and arran ed V H as shown and described, it isjapparent that whichever section of the guard plate 2 happens to be uppermost, said section maybe adjusted longitudinally upon the lowermost plate. 2- from section as ishownby dotted lines Fig. 1, to
